FAQ says: "As a rule of thumb on Squid uses approximately 10 MB of RAM per GB of the total of all cache_dirs (more on 64 bit servers such as Alpha), plus your cache_mem setting and about an additional 10-20MB. It is recommended to have at least twice this amount of physical RAM available on your Squid server. For a more detailed discussion on Squid's memory usage see the sections above." So I have 6,8 Gb cache dir = 6.8 x 10 = 68 MB + 10 MB(cache_mem) + additional 10-20 MB = 98 MB ... and to have at least twice so 98 x 2 = 196 MB ... I have 460 MB free before I start squid.... so that is 4 times more than recommended minimal amount..... Top shows squid is only using 50-60 Mb ... And if I shut down squid only 60 Mb gets freed ... I will add additional 128 RAM and see the result ... but I doubt that it will help .. maybe give me 2-5 days of uptime ... > squid maps the cache content to the memory so that it will have a fast > lookup.. > so the more your cache is being used, the more the memory is being used .. > > reduce your cache_dir or increase your memory..
